The clash of religion. We've had to coexist for hundreds of years in Bulgaria, in the Balkans, and we still don't get along. It's a reason for so much tragedy.

I was really interested in the ritual of fire dancing. I saw it when I was a kid. My parents took me to the Black Sea, it was like a tourist attraction. I think it would be hard to find a Bulgarian who is not familiar with the image. I started reading about it, and I found out there are only two villages in Bulgaria were they still do it properly, where it's not for tourists, and they were both in the Strandja Mountains.

Words physically have power to bring things into existence.

I'm interested in the way our world is defined by language, the living word. How restrained we are by the concept of language, but when you tweak it a little bit your eyes can be opened and your world is totally changed.

What's great about symbols, what a writer can do with them is provide a really vivid, interesting image, and the reader will do the rest of the work. That's always been very interesting to me. Like if I just introduce the storks, I don't have to say what they mean because the reader will do that. And if I bring in the dark history of the region, other trends come up, for example how in ancient Egypt they are associated with the souls of the dead. You can surprise yourself by introducing an image and then see how developing the story fills it with meaning that is suddenly new.

The problem is we bear grudges that go a thousand years into the past. Really, I could find people who begrudge the Greeks for doing awful things to the Bulgarians more than a thousand years ago.

All these wars, all these territories. For example, Macedonia is a disputed territory, and there are people directly to the west of Bulgaria who are in Serbia now because of where they lived when the borders were drawn but who are Bulgarian. It makes the Balkans an insanely interesting place to explore.
